Lake productivity & trophic state
Measured 2010Classification: Eutrophic. Higher nutrient levels and biological productivity, often with more algae or aquatic plant growth. Based on measurements recorded in 2010 (chlorophyll-a 19.0 µg/L).
Trophic state describes how biologically productive a lake is, based on indicators such as nutrients, algae and water clarity. It is not a swimming-safety or overall water-quality rating.
What do the categories mean?
- Oligotrophic≤ 2 µg/L · lower nutrient and algae levels, often clearer water and lower biological productivity.
- Mesotrophic2–7 µg/L · moderate nutrient levels and biological productivity.
- Eutrophic · this lake7–30 µg/L · higher nutrient levels and biological productivity, often with more algae or aquatic plant growth.
- Hypereutrophic> 30 µg/L · very high nutrient levels and biological productivity, with a greater potential for heavy algae growth and low water clarity.
Bands are summer (June–August) mean chlorophyll-a, the green pigment in algae, at the EPA 2012 National Lakes Assessment thresholds. Trophic condition can change over time and by measurement method.

Paddling
Paddling Index methodology v1.0 · calculated 2026-09-23Bass Lake has a mixed natural and developed setting, moderate open-water exposure, nearby higher-volume roads. No special watercraft restriction is identified in the current source.
Why this score?5 components
Included in the index
| Component | Rating | Points of weight | Measurement |
|---|---|---|---|
| Natural setting | Mixed | 8.2 of 35 | 33% natural land cover within 150 m of shore (10% forest, 23% wetland; 26% developed) |
| Geometric wind exposure | Good | 13.4 of 29 | mean fetch 1,504 m · 1% of sampled water within 500 m of shelter · moderate open-water fetch |
| Watercraft controls | None identified | 8.8 of 18 | No special watercraft restriction identified in the current DNR source. Motors permitted, subject to general law. |
| Public access | Not listed | — | No DNR-listed access site. Township, county and road-end launches are not in this source, so this is not evidence that access is poor — the component is excluded and the remaining weights are renormalized. |
| Road isolation | Mixed | 4.9 of 18 | nearby higher-volume roads · 67 MDOT-classified segments within 1.2 km, peak 10,234 vehicles/day |
Additional paddling considerations
These describe the lake but are not part of the v1 Paddling Index and do not change the number above.
- Wake sensitivity
- Low — wide enough that wakes disperse over most of the lake
- Aquatic vegetation
- Low — approximately 1% mapped coverage · NAIP aerial imagery (NDVI)
- Observed motorized activity
- Unknown — No lake-level measurement of boat traffic is available. Legal permission to operate motors is not evidence of use.
- Wildlife habitat potential
- Limited — 10% forest and 23% wetland cover within 150 m of shore

How to identify invasive species in Michigan lakes →
What does non-native mean?
USGS records identify non-native species that have been documented for this lake or its shoreline. Non-native does not necessarily mean invasive, and historical records do not confirm current presence.

How deep is Bass Lake?
The deepest contour on the Michigan DNR bathymetric survey of Bass Lake is 4 ft. That is the deepest depth the historical survey map records, which may differ from the deepest point of the lake itself.
How big is Bass Lake?
Bass Lake covers about 421 acres in Mason County, Michigan.
What is the average depth of Bass Lake?
The estimated mean depth of Bass Lake is 2.6 ft, calculated from the survey contours.
What fish are in Bass Lake?
Species with survey, catch or recent-stocking evidence include largemouth bass, bluegill, longnose gar, warmouth, common carp. The page shows the evidence behind each.
Is there public access to Bass Lake?
No public launch for Bass Lake appears in the Michigan DNR access data. That is not the same as the lake being private -- municipal and private ramps are not in that source.
